Hidden rail type window and door system

ABSTRACT

The present invention relates to a rail hidden type window and door system, including a lower window (or door) frame having a rail cover attached on a main window (or door) frame, a rail hidden by the rail cover and formed on a concave portion of a window (or door) of the main window (or door) frame of an inside of an inlet, and inlet gaskets mounted on a surface member and the rail cover; and a lower window (or door) member having a lower portion enhanced by a supporting portion, an extending portion having a roller supporting member on which a roller groove is formed, and a roller device mounted in the roller groove. Accordingly, the window (or door) is not removed from the rail and is stably opened and closed, while keeping the sealing state to minimize heat loss and preventing water from infiltrating into the interior.

FIELD OF THE INVENTION AND PRIOR ART

In the following description (in the field of the invention, descriptionof the prior art, problem to be solved by the present invention,description of the invention, and effect of the invention), since thedoor system is identical to the window system, the description of theinvention of the window system will be applied to the description of thedoor system.

The present invention relates to a hidden rail type window and doorsystem.

A conventional hidden rail type window and door system will be describedwith reference to the accompany drawings.

FIG. 1 is a front view illustrating a window and door system to which aconventional art is applied, and FIG. 2 is a sectional view taken alongline A—A illustrating a structure of the window and door system.

The conventional window and door system comprises a lower window framemember 1 having rails 12 and a window frame surface member 13 arrangedon an inclined line 11, the rails 12 being hidden by water-proof covers14 coupled to the surface member 13 and provided with window memberguide inlets 19; and

a lower window member 2 provided with a support member 21 formed on anextending member 23 extended from a lower portion 24 of the lower windowmember 2, a roller 22 being disposed between the rail 12 and the supportmember 21 inside an inlet 19.

However, in the above described hidden rail type window and door system,although it can prevent water from infiltrating into the interior, sincea seal is not provided, thermal efficiency deteriorates. In addition,since water infiltrates into the rail, the roller may be damaged by thewater. Since the fixing and supporting structure of the covers 14 isweak, the covers 14 may be deformed, deteriorating the open and closeoperation of the window member because of the friction between thecovers and the extending member 23 of the lower window member 2 or theroller. The roller supporting method for supporting the lower portion ofthe lower window member 2 cannot effectively support the window member.

PROBLEM TO BE SOLVED BY THE INVENTION

The present invention has been made in an effort to solve theabove-described problems. It is an objective of the present invention toprovided a window and door system that can prevent water frominfiltrating, minimize thermal loss by maintaining a sealing state, andprovide a stable open and close operation of the window member byimproving the supporting and fixing structure of a cover and a windowmember.

To achieve the above object, the present invention provides a hiddenrail type window and door system comprising:

a lower window (or door) frame having a rail cover attached on a mainwindow (or door) frame, a rail hidden by the rail cover and formed on aconcave portion of a window (or door) of the main window (or door) frameof an inside of an inlet, and inlet gaskets mounted on a surface memberand the rail cover; and

a lower window (or door) member having a lower portion enhanced by asupporting portion, an extending portion having a roller supportingmember on which a roller groove is formed, and a roller device mountedin the roller groove.

DESCRIPTION OF THE INVENTION

The embodiment of the present invention will be described hereinafterwith reference to the accompany drawings.

FIG. 3 shows a front view illustrating a window and door systemaccording to the present invention and FIG. 4 shows a sectional viewtaken along line B—B of FIG. 3.

FIG. 5 shows an exploded view of FIGS. 4, and 6 shows a viewillustrating a cover support roller and a roller device mounted on thelower window member 4.

A lower window frame member 3 comprises a window frame main body 31 andrail cover 32.

The main window frame member 31 and the rail cover 32 are provided withfixing portions 34, respectively. Inside of inlets 35 of the main windowframe member 31, concave portions 36 and rails 37 are formed. The inlets35 are blocked by gaskets 39 mounted on a surface member 38 and the railcover 32.

By forming a support portion 41 for supporting the window on the lowerwindow member 4, the lower portion 42 of the window is enhanced. Anextending portion 43 is formed on the lower portion 42 on which rollersupport members 44 are formed. A roller groove 45 is formed between theroller support members 44.

To install a cover supporting member 46, a cutting portion 47 is formedon the roller groove 45, and assembly holes 49 are formed on the rollersupport members 44 to correspond to the cover supporting member 46 and aroller device 48. The cover supporting member 46 is mounted on thecutting portion 47 of the roller groove 45, and the roller device 48 isinserted in the uncut portion of the roller groove 45. In this state,fixing pins 4 a pass through the assembly holes 49 of the roller supportmember 44 and assembly holes 4 b of the cover supporting member 46 andthe roller device 48, and are fixed by fixing clips 4 c.

To maintain a seal between the lower window frame member 3 and a lowerwindow member 4, wind shield members 3 e are mounted on the rail covers32 and 33, the lower portion 42 and the support portion 41 of the lowerwindow member 4.

Gaskets 39 having elasticity define an inlet 35 by being depressed bythe extending portion 43 in the presence of the lower window member 4,or obstruct the inlet 35 by being returned to their initial shape in theabsence of the lower window member 4. FIG. 4 shows a state where theinlet is defined by depressing the gasket 39 using the extending portion43, and FIG. 5 shows a state where the inlet is obstructed by thereturning of the gasket to its original shape.

The rail covers 32 and 33 are attached on the main window frame member31 by the fixing portions 34. However, it can be more fixedly mounted onthe main window frame member 31 by screws 3 b coupled on screwsupporting members 3 a formed on the rail covers 32 and 33. Exposedscrew groove 3 c is finished using a screw groove plug 3 d.

FIG. 7 shows a front view of a window system to which a fixed window isapplied, and FIG. 8 shows a sectional view taken along line C—C.

To mount the fixed window 6, a fixed window groove 53 is formed onsurface members 52 of the main window frame member 51. The fixed window6 is inserted into the fixed window groove, and is then finished by afixing member 61.

EFFECT OF THE INVENTION

As described above in the hidden rail type window and door system, sincethere are fixing portions 34 on the rail cover 32 and the main windowframe member 31, the separation of the rail cover 32 can be preventedwhen the lower window member 4 is removed. In addition, by using thescrews 3 b, the rail covers 32 and 33 can be more securely fixed on thewindow frame main body 31. Since the exposed screw groove 3 c isfinished by the screw groove plug 3 d, the appearance can be more clean.

The inlets 35 can be blocked by the gaskets 39, preventing water frominfiltrating to the rails 37.

Even when the rail covers 32 and 33 are deformed by impact, the windowframe can be smoothly opened and closed by the cover supporting member46, while re-covering the deformed rail covers 32 and 33.

By forming the support portion 41 on the lower window member 4, thelower portion of the window member 4 is enhanced, improving thesupporting efficiency. By providing the roller support members 44 withthe roller groove 45, the roller device 48 can be securely installed.

By installing the wind shield members 3 e on the support portion 41, thelower portion 42 of the lower window member 4 and the rail covers 32 and33, the sealing efficiency can be improved.

In addition, a mosquito net rail 3 f can be provided on an exterior sideof the surface members 38 and 52.
